Abstract

PURPOSE: To verify the aesthetic impact of mild and moderate dental fluorosis on young adult students from the UFMG using pictures with different fluorosis levels simulated in a computer program. MATERIALS AND METHODS: The sample consisted of 396 university students, randomly selected from various courses (except dentistry). These participants were shown three mouth pictures with different rates of dental fluorosis (TFO, TF2 and TF4) according to the Thylstrup-Fejerskov Index (TF). The volunteers gave an individual assessment of the pictures and graded them (from 1 to 10) based on their aesthetics. In addition, they answered if they would feel uncomfortable smiling and if they would seek dental treatment in each case. The results were submitted to a chi-square test (P < 0.05). RESULTS: The students preferred the TF4 picture to the TF2. The picture which presented no fluorosis was more often preferred than the pictures which presented some form of change due to fluorosis. Higher scores were recorded by men for the TF2 picture than by women (P < 0.05). As for the TF0 and TF4 pictures, the scores were similar among males and females. Furthermore, women reported more discomfort in smiling (P = 0.001) and a greater desire to seek out dental treatment than did men. Only 27.5% of all students stated that they knew what dental fluorosis was. CONCLUSION: Mild and moderate dental fluorosis had a negative aesthetic effect on the studied population, leading to a strong desire to seek dental treatment to change the appearance of affected teeth.

    Introduction: Dental fluorosis is a major endemic oral disease characterized by hypo mineralization of enamel caused due to consumption of water containing high concentration of fluoride during developmental stages of teeth. Aim: To assess the prevalence of dental fluorosis among 11-14 years old school children in endemic

  • An assessment of teenagers' perceptions of dental fluorosis using digital simulation and web-based testing

    OBJECTIVES: To develop a new model to establish teenagers' perceptions of the aesthetic impact of fluorosis, in the context of overall facial appearance. This web-based model was used to compare different degrees of fluorosis at any one distance, while also comparing the same level of fluorosis at different 'distances'. METHODS:

  • Adolescents' perceptions of the aesthetic impact of dental fluorosis vs. other dental conditions in areas with and without water fluoridation

    BACKGROUND: The use of fluorides for caries prevention is well established but is linked with an increased risk of dental fluorosis, some of which may be considered to be aesthetically objectionable. Patient opinion should be considered when determining impact on aesthetics. The aim of this study was to assess participant

  • Comparison of dental esthetic perceptions of young adolescents and their parents

    To compare dental esthetic perceptions of adolescents at age 13 with those of parents and to assess associations with dental fluorosis. METHODS: Adolescents aged 13 underwent dental examinations for fluorosis on maxillary anterior teeth using the Fluorosis Risk Index. Adolescents and parents completed questionnaires concerning satisfaction with adolescents' dental appearance.

    PURPOSE: With the increasing prevalence of dental fluorosis, improved understanding about esthetic perceptions of dental fluorosis is warranted. The purpose of this report was to present results concerning parents' overall satisfaction with the appearance of their children's teeth and factors related to dissatisfaction, comparing subjects with and without fluorosis and

  • Dental Fluorosis in the U.S. 1950-2004

    Before the widespread use of fluoride in dentistry, dental fluorosis was rarely found in western countries. Today, with virtually every toothpaste now containing fluoride, and most U.S. water supplies containing fluoride chemicals, dental fluorosis rates have reached unprecedented levels. In the 1950s, it was estimated that only 10% of children in

  • Mechanisms by Which Fluoride Causes Dental Fluorosis Remain Unknown

    When it comes to how fluoride impacts human health, no tissue in the body has been studied more than the teeth. Yet, despite over 50 years of research, the mechanism by which fluoride causes dental fluorosis (a hypo-mineralization of the enamel that results in significant staining of the teeth) is not

  • Racial Disparities in Dental Fluorosis

    In 2005, the Centers for Disease Control published the results of a national survey of dental fluorosis conducted between 1999 and 2002. According to the CDC, black children in the United States have significantly higher rates of dental fluorosis than either white or Hispanic children. This was not the first time that black children were found to suffer higher rates of dental fluorosis. At least five other studies -- dating as far back as the 1960s -- have found black children in the United States are disproportionately impacted by dental fluorosis.

  • "Mild" Dental Fluorosis: Perceptions & Psychological Impact

    The vast majority of research has found that patients, parents, and the general public alike view mild fluorosis (TF score 3) as a significant blemish of the teeth, one that is likely to embarrass the affected child to a degree that cosmetic treatment would be warranted.
